To on whom it may concern:

Be it known that l, FRANK G. l-lonnnooir, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Hinges, of which the following isja specification.

This invention relates to improvements in hinges and has for its object to provide a him a for use in pivotally mounting upon eac other structures, such as wood-sections, havinglcomparatively little tensile strength.

In t e drawingsFigure 1 is a side elevation of a bin e embodying m inven ion. Fig. 2 is a aim at view showing t e occludin portions broken away. Fig. 3 is an enlarge' perspective view'of the convex sec-tion of the hinge of m invention.

. I have i1 ustreted in the drswi'ngstlz'e application of-the hinge of my invention to a shoe last although said hinge is obviously adaptodior use in any structure composed'of ana ogous material and intended for male gous use; that is to say, 'where two sections of a structure of wood or like material must be pivotally connected so'as to have a limited pivotal movement in relation'to each other, combined with the utmost possible stren th of the material em loyed,'to limit such re ative movement an to prevent the accidental distortion of the entire structure resulting from injury to the hinge in use.

shown in the drawings, my formed of sections 4 and 5. or convenience, the section 4 will be referred to as the convex section and the section 5, as the concave secknuckles 6 and 7 separated by the slot 8. The curvilinear surfaces of the knuckles 6 are adapted to fit closely within the concave recess 9 in the concave section 5. Thesection 5 is rovided with a slot 10 registerin with the s 0t 8 in the section 4, and the meta lic strap member 11 is seated in place in the slots 8 and 10, bein pivoted to the section 4 by the pin 12 an ivotedto the section 5 by.the pin 13. he 11 ward movement ofthe sections 4 and 5 is limited by the plane faces 14 and 15 with which the sections.

4 and 5 are respectively rovided; the sections 4 and 5 being norma ly held in the osition illustrated in Figs. 1- and 2 of the rawings by means of the coil-spring 16, for the accommodation of the ends of which the section 4 is provided with the chamber 17 and the section 5 is provided with the chamber 18. as illustrated in Fig. 2.

these faces the section 5 is contouredjto regissi t ter by being provided with: the teen l against such dislocatiemetheslots hinge is stressfisealcu sited to pull thetniemberal-" l.

and 5 apart, causing the ins 12 and wear, or be drawn, into t e compa'rati soft material of the sections. 4 and} wear resulting'i'iii the displacement hinged connection and the dislocatio sections 4 and 5 with reference to one shoulder 19 having it horizontahplane' face 20 and a vertical plane face 2l,.'=and with groove 22 forming the faces23-and 2 l i,1w,r. are adapted to register the faces 21 respectively. a iurther sat "guard are rectilinear and in alinernent at th toms as illustrated in sectiozg'in'llig numerals 25 and2 6, sothatwhenthe strap 1 1 is seated-in piacefltslower edge fits snugly ag inst the plene'surfac T25 and 26; formed by the bottoms of thesldtsSend 10-2,

By the described structural haveisafeguarded the members 4 and i'i'against dislocation by any force lessthan will mutilate or crush the structure of the sections themselves.

Having fully described-my invention; what so I claim as new and desire to have secured to me b the grant oiLetters Patent, is:

1. n a hinge, the combination of a con vex section providedwith two knuckles separated by a slot; a concave section provided with a'concave recess adapted to register with said knuckles and slotted to register with the slot in the first-harried section; a strap seated in said slots and having rectihn:

ear engagement with the bottoms of saidflgp slots; the convex section being provided 1 with a shoulder beneath the knuckles, and the concave section being grooved beneath its concave recess to register with said shoulder; and a spring whereby said shoulder is lo normally kept in engagement with the concave section, substfimtially as described.

2. In a hinge, t e combination of a convex section providcd with two knuckles separated by a slot; a concave section provided 1R with aconcave recess ada ted to register with said knuckles and slotte to register with the Ipins, his" at slotin-the first-named section; a strap seated the ends of said spring, substantially as de in said 'slqts and having rectilinear engagescribed. t
